6 Operation
6.1 Cold water throttle disc
Note
Observe the flow direction when replacing the throttle
disc!
Note
The installed cold water throttle disc can be replaced by
a corresponding throttle disc if required (see table
below). The colour indicates the maximum inserted
volume flow.
The throttle disc limits the amount of cold water to the heat
exchanger and prevents the hot water supply from exceeding the
calculated volume.

6.2 Strainer
Caution!
Lock the unit and relieve the pressure before any work
with the strainer.

CD0000430
The strainer collects dirt and its filter can be removed for inspection
and cleaning.
6.3 Thermostatic temperature lead
module (TTV)
Note
The valve flow can also change by connecting to the
capillary pipe Ø 6 mm.
Note
A too high value can cause the heating water return
temperature to rise.
Note
A too low maintenance temperature setting can lead to
longer waiting times when preparing domestic hot water.
Set the TTV line temperature to approximately
15 K
below the
network flow temperature.
CD0000429
The thermostatic temperature lead module (TTV) serves the heat
retention function of the supply line. It is used on units last or in
greater distance from the main line and prevents the risers from
cooling down when not dispensing.
The valve is adjustable and the setting range is printed on the cap.
The temperature is measured by a sensor inside the valve.
